R$> Sure. Once my code is written I do not want to pay the overhead

I agree. The Python standard library does very minimal
type-checking. Instead, the philosophy is that if a user supplies an
argument of the wrong type, an exception will be raised when the value
is actually used. In many cases, the traceback is as clear as one
generated by an explicit type check.
